why not? couldnt you just make an illusion that it looks 3d?

probably a waste of your time.

How would that be any different than actual 3D graphics? Whenever you're seeing a 3D image on your screen (assuming it isn't pre-rendered,) your computer takes the 3D space in memory, and figures out what the 2D image of what the camera is looking at. On top of which, you can't "fake" an environment the user actually moves around. If they're going to walk around it, it needs to be able to be seen from any given angle at any given time.

Turing simply doesn't have the power to do this kind of thing effectively. Turing is meant to teach the basics of programming to absolute beginners. For almost anything beyond that, you'll need to learn a proper language.

As Tony said, it is theoretically possible to do this, if you wanted to. But your final product would be next to worthless, and probably a waste of your time.

Don't you remember old 3D (2.5D) which used static 2-D image that were streched and or scewed to make the appearence of depth. Non environment (aka enemies, items, etc.) were 2-D sprites drawn at usually 8 angles to create the illusion of direction and simply shrunk and grown to show distance. Given how long we've been doing butchered 3-D it is definately completely possible to do a 3-D FPS in turing if your willing for it to look like shit. Hell TBH, you could probably remake say Duke-Nukem 3D, or Wolfenstein 3D if you were good enough and had the time and effort.

whats an FPS exactly? =\

FPS = First Person Shooter

or

FPS = Frames Per Second[b][i][u]
